09724874 · 2017-08-08 ·

A method for manufacturing substantially longer structural insulated panels through lamination without sacrificing thermal efficiency and structural integrity. The method includes laminating an insulating structure in between a lower sheet of serial panels and an upper sheet of serial panels. The individual structural panels of the lower sheet of serial panels are spliced together with a plurality of lower splice plates. Similarly, the individual structural panels of the upper sheet of serial panels are spliced together with a plurality of upper splice plates. The plurality of upper splice plates is positioned offset from the plurality of lower splice plates. The resulting elongated structural insulated panel retains its characteristics due to the positioning of the splice plates and their integration into the manufacturing method.
